RT8110B

Compact Wide Input Range Synchronous Buck DC/DC

PWM Controller

General Description

Features

z 10V to 28V Wide Input Voltage Range

The RT8110B is a compact fixed-frequency PWM controller

with integrated MOSFET drivers for single power rail

synchronous single-phase buck converter. This part

features an internal regulator that allows wide input voltage

range operation. The RT8110B utilizes voltage-mode

control with internal compensation to simplify the

converter design.An internal 0.8V reference voltage allows

low output voltage application. The switching frequency

is fixed at 400kHz to reduce the external passive

component size to save board space. The RT8110B

provides under voltage protection, current limit, over current

protection and over temperature protection. The low-side

MOSFET R_DS(ON)is used to sense the inductor current

for over current protection.
